The sister of a dad shot dead outside his home by four gunmen has promised to look after his children in a heartbreaking tribute.
Christopher Anderson, 36, was gunned down on Saturday after he chased the shooters out of his home in Gailes, near Ipswich in Queensland.
Family and friends posted eulogies for Mr Anderson to Facebook with his sister Lisa Conlon mourning the loss of the young dad.
'Rest in dreamtime little bro. I'm absolutely shattered beyond words. I'm sorry this has happened to you,' she wrote.
